Yoko Ono has warned that Beatles tracks will not be available to download on to iTunes in the near future.

John Lennon's widow has disclosed that the owners of the Beatles rights are in a dispute with Steve Jobs, Apple's co-founder. Miss Ono, 77, said: "Steve Jobs has his own idea and he's a brilliant guy. There's just an element that we're not very happy about. Don't hold your breath."

The Beatles rights are held by Apple Corps, which settled a trademark deal with the computer company in 2007, in which Miss Ono, Paul McCartney, Ringo Starr and Olivia Harrison own equal shares.
